How to distinguish the good and bad and common use of webbing?
We can identify whether the webbing is good or bad according to the material of the webbing, color cast, burrs, etc. The following are some identification methods of webbing:
Polyester webbing: It melts and burns near the flame, dripping and bubbling does not continue to burn immediately. It tastes like lettuce. Round. Light. Brown to dark gray, beaded. Polyester fabric ribbon: It melts and burns near the flame, dripping and foaming can continue to burn. There are very few with weak smoke, sweet and hard round, black or light brown. Flax fiber and hemp fiber. Flax fiber and hemp fiber are all flammable just before the flame, burning quickly, the flame is light yellow, and black smoke is emitted. The difference between the smell released by the two during burning and the embers after burning is that the burning of cotton tape gives off the smell of paper, and the burning of hemp cotton gives off the smell of grass ash; Then a small amount of off-white powdery embers is caused.
Cotton and polyester cloth: cotton (polyester) is also known as polyamide fiber, which is quickly curled and melted into a milky white gel near the flame, which melts and drips in the flame and bubbles. There is no flame when burning, and it is difficult to burn again after leaving the flame. The lettuce flavor is released, and the light brown melt does not mash easily after refrigeration.
Polyester fabric, also known as polyester fiber fabric, is easy to ignite, and it melts near the flame. When burning, it melts and emits black smoke from the exhaust pipe. It is a light yellow flame and releases a fragrant smell. After burning, the embers are brown lumps. Twisted. Temperature resistance: The cotton webbing has excellent high temperature resistance. When the temperature is below 110 °C, it can only cause the water on the webbing to volatilize, and it is not easy to damage the chemical fibers. Therefore, the cotton webbing is used at room temperature. The webbing is harmless, thus improving the washability and durability of the cotton webbing. Acid resistance: Cotton webbing is relatively resistant to alkali. Cotton webbing will not be damaged in alkaline solution. This feature is beneficial to washing of environmental pollution after taking it, disinfection and sterilization to remove residues. Coloring, garment printing and various processing techniques are carried out for cotton webbing to produce a large number of excellent varieties of webbing.
